Coffee

For best flavor, finely and freshly ground strong coffee beans should be added to a liquid that is heated to 93°C / 200°F, which is the ideal brewing temperature to make regular drinking coffee. Hotter liquids will make for an unpleasant taste. Coffee extract is not a viable replacement for frozen desserts, because it adds water and has an unnatural coffee flavor. Homemade coffee extracts are recommended for flavoring aerated still-frozen desserts, but, for example, in a coffee semifreddo, it is possible to steep the heavy cream, chill it, and then whip it. Soluble coffee is, while not the ideal, a decent substitute.
